I think when you buy straight from factories, they only do bulk sales?

A lot of textile factories don’t have online presence because they don’t need one. They have regular clients and so they build on those relationships and rely on word-of-mouth insider referrals. For example, a cotton factory would have clients like bedsheet manufacturer, curtain maker, fabric printing plant, etc.

In short, I don’t think online searching alone is enough. You’ll probably have to dig deeper or find those connections.
